Second row passenger carpet soaked

[optimusprime]

Cleaned the Yukon today and when I took the second row mat out (which was dry) I found the carpet was wet on the passenger side. I pulled the trim and didint notice any leaks or signs of leaks. The insulation underneath the carpet is totally saturated and the carpet smells like mildew but only in the passenger leg bay. What would cause this? Everything around that area is dry.

Hole in the floor or leaking sunroof?

Rear AC leaking?

Alex, I'll take Leaking Sunroof Drain for $50.

Does the sunroof drain empty in the second row? How would the water be getting in there?
